Abstract: The geological information database of Dongzhouyao Mine Field was built. Taking Dongzhouyao Coal Mine as the research object by using DepthInsight 3D modeling software, and complicated structure, three different scales of 3D geological models were constructed by using techniques such as “fault intersection treatment”, “small layer modeling”, “Delaunay triangulation grid” and “truncated mesh generation”. The mine field-scale model generally displays the structure in the minefield in three-dimensional form. Based on it, the Kriging algorithm is used for interpolation calculation to predict the distribution of igneous in Shan 4^# and 5^# coal seams; the scale model of seismic exploration area reveals the coal seam morphology and structural characteristics in this area. Based on this model, 8 planned working faces such as 8402 and 8403 are simulated to realize the visualization of underground structure; the working face scale model is the most accurate model. Taking 8100 face as an example, the method of high-precision 3D geological modeling and dynamic updating of working face is explored.
